Ian Pearce, consultant ophthalmologist, Royal Liverpool University Hospital, commented on the approval: "This is an important step forward in the management of patients with RVO because the disease is difficult to treat with few available options."

Lucentis was developed by Genentech and Novartis. Genentech has the commercial rights to Lucentis in the US. Novartis has exclusive rights in the rest of the world.

Novartis also announced successful results of a trial involving cancer drug Glivec (imatinib). The treatment showed significant overall survival benefit for patients with gastrointestinal stromal tumours GIST who took the drug for three years post-surgery when compared to one year.

The results show that at five years, 66 per cent of patients taking Glivec for three years remained free of cancer recurrence compared to 48 per cent who had received Glivec for only one year.
